As previously announced, Visa will only assign eight-digit issuing BINs for new requests effective in April 2022; six-digit BINs will no longer be assigned. Given the potential size and scope of changes, Visa recommends beginning analysis and planning now.
The first step to prepare for the migration to the new numerics standard is to analyze the impacts to your organization by reviewing back office processes. Examples where impacts from expanding the issuing BIN may occur include billing, reporting, user interfaces, application interfaces, enrollment forms, or anything that currently uses the six-digit issuing BIN. Visa encourages merchants to complete an impact analysis and begin development of the necessary changes prior to peak season of calendar year 2020, in order to stay on track for the April 2022 VisaNet Business Enhancements release.
